Capable of laser oscillation light source is wavelength-locked by an optical signal injected

摘要

Is wavelength-locked by an optical signal to be injected capable of laser oscillation light source (101), a variety of ways, I will explain the system, the equipment. (101) having an anti-reflection film on the facets of one or more capable of laser oscillation light source such as a Fabry Peron laser diode. Accept the spectral slice of the optical signal broadband light source from a (113), capable of laser oscillation source (101), the bandwidth of the optical signal to be injected, the output wavelength of the (101) thereof capable of laser oscillation source I want to lock the wavelength. As is reflected back from the front facet after being wavelength-locked light to be injected is amplified and biased capable of laser oscillation light source (101), current pump (141) operates as a reflective play a semiconductor optical amplifier . (141) is to suppress laser oscillation outside the bandwidth of the incoherent optical narrowband optical signal that is externally injected into the laser oscillation light sources (101) is injected into the current pump, I want to bias capable of laser oscillation light source (101).
